Embodiment 1

[0022] A kind of violet ceramic pigment, the parts by weight of each component are:

[0023] 2 parts of tin dioxide, 0.3 parts of chromium oxide green, 0.5 parts of silicon dioxide, 10 parts of zinc oxide, 10 parts of citric acid, 1 part of chrome tin amethyst seed, 0.1 part of sodium fluorosilicate.

[0024] Its preparation method comprises the following steps:

[0025] Mix and stir the raw materials evenly to obtain a uniform mixture, then grind it thoroughly for 4 hours; calcinate the mixture at 500°C for 8 hours; after calcining, add the powder into pure water that is 20 times its weight, stir for 30 minutes, and then filter out the water , drying; the dried solid is ground by a ball mill and passed through a 350-mesh sieve to obtain a violet ceramic colorant.

Embodiment 2

[0027] A kind of violet ceramic pigment, the parts by weight of each component are:

[0028] 4 parts of tin dioxide, 0.5 parts of chromium oxide green, 0.65 parts of silicon dioxide, 15 parts of zinc oxide, 15 parts of citric acid, 3 parts of chromium tin amethyst seed, 0.25 parts of sodium fluorosilicate.

[0029] Its preparation method comprises the following steps:

[0030] Mix and stir the raw materials evenly to obtain a uniform mixture, then grind it thoroughly for 6 hours; calcinate the mixture at 550°C for 10 hours; after calcining, add the powder to 25 times its weight in pure water, stir for 60 minutes, and filter out the water , drying; the dried solid is ground by a ball mill and passed through a 400-mesh sieve to obtain a violet ceramic colorant.

Embodiment 3

[0032] A kind of violet ceramic pigment, the parts by weight of each component are:

[0033] 3 parts of tin dioxide, 0.5 parts of chromium oxide green, 65 parts of silicon dioxide, 15 parts of zinc oxide, 20 parts of citric acid, 3 parts of chrome tin amethyst seed, 0.5 part of sodium fluorosilicate.

[0034] Its preparation method comprises the following steps:

[0035] Mix and stir the raw materials evenly to obtain a uniform mixture, then grind it thoroughly for 5 hours; calcinate the mixture at 525°C for 9 hours; after calcining, add the powder into pure water whose weight is 22.5 times, stir for 45 minutes, and filter out the water , drying; the dried solid is ground by a ball mill and passed through a 375-mesh sieve to obtain a violet ceramic colorant.

Abstract

The invention relates to violet ceramic pigment and a preparation method thereof, and belongs to the technical field of ceramic pigment preparation. The violet ceramic pigment comprises the following raw materials by weight: 1 to 5 parts of stannic oxide, 0.2 to 0.5 part of chromium oxide green, 0.5 to 0.8 part of silicon dioxide, 10 to 20 parts of zinc oxide, 10 to 20 parts of citric acid, 1 to 5 parts of chrome-tin amethyst, and 0.1 to 0.5 part of sodium fluorosilicate. The preparation method comprises the following steps: mixing the raw materials uniformly, stirring to obtain a uniform mixture, and carrying out sufficient grinding for 4 to 6 hours; calcining the mixture powder at 500 to 550 DEG C for 8 to 10 hours; adding the calcined powder into purified water which is 20 to 25 times of the calcined powder in weight, stirring 30 to 60 minutes, filtering to remove water, and drying; grinding the dried solid with a ball mill, and sieving with a 350 to 400-mesh screen, so as to obtain the violet ceramic pigment. The violet ceramic pigment is narrow in particle size distribution, stable in color generation, low in color difference variation, and high in stability under a high-temperature condition; moreover, the preparation process is simple, the equipment requirement is low, and industrial production is easy to realize.

Description

technical field [0001] The invention relates to a ceramic color material, in particular to a violet ceramic color material and a preparation method thereof, belonging to the technical field of ceramic color material preparation. Background technique [0002] Ceramics are various products made of natural clay and various natural minerals as the main raw materials through crushing, kneading, molding and calcination. Painted pottery, also known as ceramic painting, is an art in my country's long-standing "national quintessence" - ceramic art. Painted pottery is beautifully made, mainly clay pottery, the color is painted before firing, and the texture is fine, so it is not only a practical vessel, but also has high artistic value. [0003] Ceramic pigments, also known as pigments or color materials, are powdery decorative materials for colored ceramics formulated with color bases and fluxes or additives. Pigment = color base + flux, the color base is the chromogenic substance ...
